> When HoodieIncrSource is used to fetch the update from another Hudi table, the IncrementalRelation will be used to read the data. But it has a performance issue because the column pruning and predicate pushdown don't happen. As the result, Hudi reads too much useless data.
> By enabling the column pruning and predicate pushdown, the data to read is reduced dramatically.
